13 Claims.

1'5 Another object of my invention is to provide such a. device that is relatively inexpensive to manufacture, relatively simple instructure, and easy in operation.

A still further object of my invention is to provide such a means which is relatively'inconspicuous, which takes up a minimum of room, and which does not interfere with the normal'operation of the commode.

To accomplish the above, and other important objects, my invention in general embraces the concept of introducing into the waste pipe water under suflicient pressure to fiush'any obstruction therefrom. More specifically my invention includes a device in communication with a water line under the normal city pressure and means 'for introducing such water under said pressure to the waste line.

In the accompanying drawing there is depicted one embodiment of my inventive concept, it being understood, of course, that various modifications may be made therein without departing from the scope of my invention. In the drawing, in which similar numerals indicate the same parts:

Figure 1 is a top plan view of a device constructed in accordance with my invention, with a portion of the commode being'broken away.

Figure 2 is a side elevation of the device shown in Figure 1 with a portion of thecommode being broken away. 7

Figure 3 is a detailed view of the valve construction shown in longitudinal section.

Figure 4 is a cross-sectional viewof the valve shown in Figure 3, taken along the line 4-4'0f Figure 3.

Referring more particularly to Figures 1 and 2, there is shown a conventional commode designated by the numeral I, and provided with the usual seat covers 2 and 3, hinged as at 4 to an overhanging lip 5. The lip 5 serves not only as a base on which to pivot the covers 2 and 3, but preferably projects a suflicient distance to conceal the'discharge' mouth of my invention.

Water is admitted to the commode through pipe '6, which extends to the usual flush box, and the I 5 conventional waste line I is provided. However, it will be noted that the commode is cut away around the end of the waste pipe to form 'a shouldered seat -8 adapted to receive the discharge mouth of mymechanism.

The discharge mouth 9 is preferably cupshaped and made of rubber or some other material that will form a water-tight seal with the shouldered seat 8. The discharge mouth 9 is mounted upon an arcuate pipe i which extends through an aperture l2 formed near the top and at the rear of the commode. A rubber sleeve 13 is fitted in the aperture l2 which, in conjunction with the pipe II, forms a seal and prevents splashing or overrunning of the water in the commode.

By means of an elbow M, the arcuate pipe l l is secured to a section of pipe which, in turn, is threaded in an elbow I 6. A pipe H is likewise fitted into elbow IS. The pipe l! is rotatably mounted in bearings i8 and I9, and, asshown in 'Figure'l, a check valve 2-1 is interposed in pipe [7. This check valve is adapted to permit the passage of water in only the direction indicated by the arrows in Figure 1, and serves to prevent any counterflow of water. 7

A bracket 22 is fixedly secured tc the rotatable pipe 11 and one end of a lever 23 is pivoted to this bracket. The opposite end of the lever 23 is pivoted to a crank 24, provided at one end with 3"; a foot treadle 25 and mounted at its opposite end on a bracket 28 which is secured-to the floor.

It will, therefore, be seen that upon actuation of lever 26, the pipe it. will be oscillated in a counter-clockwise direction which, in turn, will throw the discharge mouth 9 into operative position where it fits intothe seat 8 of the waste line, as indicated by the dotted lines in Figure 2. A helical spring '2"! is mounted upon pipe 6 i, so that the discharge mouth '9 will be returned to inoperative position, bearing against the rubber sleeve Hi, When the foot is released from the treadle 25. v,

As shown in Figures 1 3 and 4, I have provided a conventional type of rotary valve designated 1 generally 28, which is opened when the discharge mouth 9 is in operative position, and thereby admits the water under city pressure to the discharge mouth 9. As best shown in Figure 3, th s valve comprises a casing 29 which is securely mounted upon a section of pipe 3| which is in open communication with the water line of the house. The casing 29 forms a chamber 32 in which there is mounted a stationary wall 33 provided with an opening 34.

The pipe l? is rotatably journalled, in a watertight fit, within th casing 29, and there is securely mounted upon the pipe I! a disk 35 provided with an opening 36, which is adapted to register with the opening 34 when the pipe I! is rotated to operative position. Passages 31 extend through the pipe I! and the shoulder on the disk 30, so that water admitted through the ports 34 and 36 may enter pipe I! and pass to the discharge mouth 9.

Of course, it will be obvious that any other type of valve may be used in lieu of the specific valve 28 shown in the drawing.

A second check valve 38 may be placed in line 3| to prevent any flow of water from the commode into the main water system of the house. Of course, any number of check valves may be used to insure that there shall be no such counterflow of water, but I have found in actual practice that two have always been sufiicient and in most cases a single check valve suffices.

The advantages of my invention are believed to be obvious. The mechanism in general is relatively inconspicuous, and will, take up no appreciable space in a bathroom or lavatory. The device is, of course, relatively inexpensive and may be readily operated. By means of this device water under a relatively high pressure, as maintained in most municipal water systems, may be immediately introduced into the mouth of the drain line, and the pressure of this water is sufficient in practically all cases to remove any normal obstructions in such waste line, and to thoroughly flush the line.

While I have shown one specific form of structure, it will, of course, be obvious that various modifications may be made in the individual elements and their combined assemblage without departing from the scope of my invention, which is to be determined solely by the appended claims.
